METHOD OF WEAVING FABRICS.

Specification of Letters Patent.

Patented Mar. 8, 1910.

Application filed December 14, 1903. Serial No. 185,165.

To all whom it may concern:

Be it known that I, JOHN C. BROOKS, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Methods of lVeavingFabrics, of which the following is a specification.

My invention relates to the weaving of a fabric in which the figuring isformed by the use of two warps of difierent colors, one warp forming oneface of the fabric the other warp forming the other face of the fabric;and transferring the warp threads from one face to the other, to formthe figuring, and in further forming another pattern, by crossing one ofthe warp threads of the group with the other warp thread of the group.And my invention further consists in making each first pick, and eachthird pick a duplicate of each other.

The object of my invention is to save time and expense in preparingdesigns, and pattern cards for such fabrics, instead of as ordinarily,designing and cutting separately cards for each pick. I attain thisobject by the method shown in the drawings in which Figure 1 is a planview of a section of fabric woven by my method, but exaggerated to showthe weave, Fig. 2 being an edge view of threads-1 and 2, Fig. 3 being asimilar view of threads 7 and 8.

The odd numbered warp threads, as 1, 3, 5 and 7 are the bottom warpthreads; the even threads, as 2, 4, 6 and 8 are the top warp threads,and are interwoven with the weft threads, designated by letters, asfollows. First pick, a, and every fourth pick thereafter as, a, e, i,and m, each alternate group of warp threads, as 1, 2; 5 and 6 are leftdown, and the opposite alternate groups as 3, 4; 7 and 8 are raised, anda pick of weft inserted. At the second pick, I), threads 2, at, 5, 6 and8 are raised; at this pick, and at the next second pick, the change inposition of the warp threads are effected to produce patterns, viz-warpthread 5 is brought to the surface, as well as thread6; on the thirdpicks, 0, g, 70, as before stated, the threads in groups are opened andpick 0 inserted, on the fourth pick, (Z, threads 2, 1, 5, and 7 areraised and pick d inserted, on the fifth pick, 6, the threads, ingroups, are opened and pick 6 inserted, on the sixth pick, f, threads 2,4, 5, and 7 are raised and pick f inserted;

on the seventh pick, 9, the threads are opened in groups and pick 9inserted, on the eighth pick, it, thread 2 is raised to the left of itsmating thread, thread to the right of its mating thread, and threads &and 7 are raised, and pick it inserted; on the ninth pick, z, thethreads are opened in groups and pick 71 inserted; on the tenth pick, j,thread 4: is raised to the left of its mating thread, thread 7 to rightof its mating thread, threads 2 and 5 raised and pick j inserted; on theeleventh pick, 70, the

threads are opened in groups and pick is inserted; on the twelfth pick,Z, thread 1 is raised to the left of its mating thread; thread 5 israised to the right of its mating thread; threads 4 and 7 are raised andpick Z inserted; on the thirteenth pick, m, the threads are separated ingroups and pick m inserted; and on the fourteenth pick, a,

thread 4: is raised to the left of its mating thread, thread 7 to theright of its mating thread, threads 2 inserted.

The raising of the threads, on the so termed even pick, may be varied atwill according to the desired effect sought.

I claim;

1. The herein-described method of weaving a double-faced fabricpresenting at its opposite faces like patterns differing in color ormaterial formed by warp-threads and weft threads, which consists individing said warp into substantially two parts, one to form the upperface of the cloth the other to form the lower face of the cloth, reedingthe successive warp threads into the reed to form groups; separating thewarp threads to form sheds in the following manner, viz-for the firstpick, raising each alternate group and inserting a pick of weft, thenclosing the warp shed, and to form a new shed for the second pick, andto make patterns, raising in some portions all the threads of one warpand in the other portions all the threads of the other warp; inserting apick of weft then for the third pick raising each alternate group leftdown at the first pick and inserting a pick of weft, closing the warpand repeating the foregoing for any number of picks desired.

2. The herein described method of weaving a fabric presenting at itsopposite faces like patterns differing in color formed by warp threadsand weft threads, which consists in dividing the warp into substanand 5raised and pick it tially two parts, one to form one face of the fabric,the other to form the other face of the fabric; separating theWarp-threads to form sheds in the following order, Viz; the first pickraising each alternate warp thread of both warps, inserting a pick ofweft, closing the warps; then for the second pick raising in someportion all the threads of one warp and in the other portions raisingall the threads of the other Warp, inserting a pick of Weft and closingthe warp shed; for the third pick raising the alternate warp threads,left down at the first pick, inserting a pick of weft; repeating theforegoing for any desired number of picks until the clesired pattern hasbeen formed, then repeating the formation of the' sheds for the firstand third picks but for the aforesaid second pick raising a warp threadto the right and for the second second pick raising the same nesses.
